An ordinary high school boy, Kisaragi Ikuto, is summoned to another world and embarks on a journey to defeat the Demon Lord.

After about a year of travel, Ikuto finally defeats the Demon Lord, but is fatally wounded in a mutual strike from the Demon Lord's final attack.

Alicia, the miko who summoned him and traveled with him, performs a world transfer to save Ikuto's life, binding his soul to her own body.

This is a romantic comedy about the protagonist, who has transformed from a high school boy into a silver-haired girl in modern Japan, and experiences a slightly risqué daily life at school.
